Answer:

There are 52 cards in a deck. Four kings and 13 clubs. So the probability of choosing a king or a club is 17/52. The probability that it's both a king and a club is 1/52 because it's only one king that's a club. Hence for drawing a card from a deck, each outcome has probability 1/52. The probability of an event is the sum of the probabilities of the outcomes in the event, hence the probability of drawing a spade is 13/52 = 1/4, and the probability of drawing a king is 4/52 = 1/13.

Answer:

18° and 72°

Step-by-step explanation:

Complimentary angles form 90°

We have an angle (x) 4 times larger than the other (y).

Well actually, a system of equations isn't required, so forget about x and y, just divide 90 by 5. This gives you 18, one of the angle's measurements is 18°. Multiply 18 by 4 and get 72. The other angle's measurement is 72°.

Delta furnishings received an invoice dated may 10 for a shipment of goods received june 21. The invoice was for a $8400.00 less

djyliett [7]

Answer:

The right solution is:

(a) $1,940

(b) $2,813

Step-by-step explanation:

Given:

Invoice amount

= $8,400

Discount 1

= 33.33%

Discount 2

= 12.5%

So,

The net payable amount will be:

= $8400\times [1 - \frac{100}{300} ]\times [1 - \frac{12.5}{100} ]$

= $8400\times \frac{2}{3}\times 0.875$

= $4900$ ($)

Now,

(a)

Amount paid will be:

= $2000\times 0.97$

= $1940$ ($)

Balance still to be paid will be:

= $4900-2000$

= $2900$ ($)

(b)

Amount paid will be:

= $(4900- 2000)\times 0.97$

= $2900\times 0.97$

= $2813$ ($)

Balance still to be paid will be:

= $2000$ ($)

Thus the above solution is the appropriate one.

To make one recipe, Lina needs 1/4 cups of sugar. For another recipe, she needs 1/2 cups of sugar. How much sugar does she need

KiRa [710]

Answer:

She needs 3/4 or 0.75 cups of sugar.

Step-by-step explanation:

1/2 = 2/4

2/4 + 1/4 = <em>3/4</em>

<em></em>

Then to get it as a fraction, you divide 3 by 4 and you get 0.75. Hope this helps!!
